Detailed reading This text can mainly divided into two stages Stage 1 : The development of the earth (para 1— 3) Stage 2 : The development of life (para 4— 5)

Para. 1&2: the formation of the universe and the earth Answer the following questions: 1. About how the universe began, which theory is widely accepted? 2. What form（形状） was the earth after the “Big Bang”? 3. What made up the earth’s atmosphere after the earth exploded?

Big Bang A solid ball The earth Atmosphere

(4) What appeared as the earth cooled down? Water appeared water is important for the beginning of life on the earth.

Why is water so important for the beginning of life? Because water allowed the earth to dissolve harmful gases into oceans and seas.

Stage 2 The development of life

Analysing water How life began on the earth 1. small plants in water 2. shellfish and all sorts of fish green plants on land forests 3. insects (on land) 4. amphibians (on land in water) (onland) 5. reptiles (onland) 6. dinosaurs (onland) small clever 7. mammals (on small clever animals withhands and animals with and feet 8. human

7. What life developed after mammals? small clever animals

1. Who are the small clever animals with hands and feet? 2. Are they taking care of the earth well? Why?

Para. 5 the arrival of humans and their effects on the earth Answer the following questions: 1. What problems have been caused by humans to the earth? 2. What does the last sentence mean?

Because they are putting too much carbon dioxide into the atmosphere, which prevents heat from escaping from the earth into space. The earth may become too hot to live on.

Can you put the order of development of life into a time line? 1. Insects and amphibians appeared. 3 3. The earth became a solid ball. 9 5. Reptiles appeared. 2 7. The earth was a cloud of dust 6 9. Shellfish and other fish appeared. 12 11. Clever animals with hands and feet appeared 8 10 2. Dinosaurs appeared. 4. Small plants grew on the water. 7 6. Plants began to grow on dry land. 4 8. Water appeared on the earth 1 10. The universe began with a “Big Band”. 11 12. Mammals appeared. 5
